It's been [almost] a year since Google rebranded the Android Market as the Google Play Store, and to celebrate, the big G is planning on kicking off a bunch of content sales all over the world. And in some parts of the world, where today is tomorrow (eg, March 6th), the sale has already begun. Our Australian readers will be happy to know that the Play Store's big 1-year bash is well on its way - various movies, books, apps, and games are all on sale at low, low prices.
